Since most avionics manufacturers see software as a way to add value without adding weight, the importance of embedded software in avionic systems is increasing. Most modern commercial aircraft with auto-pilots use flight computers and so called flight management systems (FMS) that can fly the aircraft without the pilot's active intervention ...
The integrated modular avionics concept proposes an integrated architecture with application software portable across an assembly of common hardware modules. It has been used in fourth generation jet fighters and the latest generation of airliners .
Avionics – are the electronic systems used on aircraft, artificial satellites, and spacecraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions.
ARINC 653 (Avionics Application Software Standard Interface) is a software specification for space and time partitioning in safety-critical avionics real-time operating systems (RTOS). It allows the hosting of multiple applications of different software levels on the same hardware in the context of an Integrated Modular Avionics architecture. [1]
The datalink control and display unit (DCDU) on an Airbus A330, the pilot interface for sending and receiving CPDLC messages.. Controller–pilot data link communication (CPDLC) is a means of communication between controller and pilot, using data link for ATC communication.
IMA modularity simplifies the development process of avionics software: . As the structure of the modules network is unified, it is mandatory to use a common API to access the hardware and network resources, thus simplifying the hardware and software integration.
Although the consortium started with a focus on avionics, the applicability of the technical standard and its associated data model have become much broader. The standard enables software developers to create and deploy a wide catalog of applications for use across the entire spectrum of real-time systems through a common operating environment.
Abstract representation of a Fly-By-Wire flight system. A flight control computer (FCC) is a primary component of the avionics system found in fly-by-wire aircraft. It is a specialized computer system that can create artificial flight characteristics and improve handling characteristics by automating a variety of in-flight tasks which reduce the workload on the cockpit flight crew.
